Bloody Convector

Mark_27

This last baseboard on the return loop just refuses to allow water flow. After purging over a gallon of water( and very little air) the side opposite the air vent remains cold. Any ideas on how to remove the trapped air??

Are you sure? You just sayed you didn't get air. Try to much baseboard or something with the circulator.

At what pressure is the boiler operating, how high above the boiler is this baseboard you are having problems with? Are you trying to purge with the circulator running? If so shut it off and purge.
